This is a really bad idea. The implications of RFIDs in consumer items haven’t been properly explored.

- coupled dependencies – are you going to rely on being able to make a purchase with your keys, given the above valet scenario and others? What happens if you lose your keys, how many different functions need to be closed down or tracked to protect you?

- security issues – RFIDs can be easily read and duplicated/spoofed given the right equipment. Many POS purchases require no other authentication than a swipe.

- consumer ignorance – banks, retailers and POS suppliers haven’t educated the public on RFID risks and benefits.

- privacy issues – the ability to read all unique identifiers on a person at once — and without their knowledge — completely undermines the privacy of ordinary activities

This really is a big deal. The only real exploration by companies on this subject is the benefits —– to them.
